Online Presentations (1-2 of 2)

This learning module introduces nanoHUB users to some of the available simulators. The simulators discussed are FETToy, nanoMOS, Schred, CNTbands, and QDot Lab. For each simulator, a brief introduction to the simulator is presented, followed by voiced presentations featuring the simulator in action. Upon completion of this module, users should be able to use these simulators to gain valuable insight into the electronic and physical properties of cutting edge devices.

We have developed a self-consistent atomistic simulator for CNTFETs.
Using the simulator, we show that a recently reported high-performance
CNTFET delivers a near ballistic on-current. The off-state, however, is
significantly degraded because the CNTFET operates like a
non-conventional Schottky barrier transistor. Design optimization for
significantly improving the off-state is explored. We have also assessed
how the CNTFET compares to the state-of-the-art Si MOSFET and the
potential of CNTFETs for high-frequency applications.
